HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Errors:
A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Bad start tag in “img” in “head”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Stray end tag “noscript”.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
Element “div” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
The element “button” must not appear as a descendant of the “a” element.
Bad value “100%” for attribute “width” on element “img”: Expected a digit but saw “%” instead.
Attribute “attr-link” not allowed on element “a” at this point.
Start tag “a” seen but an element of the same type was already open.
End tag “a” violates nesting rules.
Cannot recover after last error. Any further errors will be ignored.
